I’m amazed the Philips Hue Bridge can’t be powered by PoE right out the box. Considering it requires an Ethernet connection you would think Philips would have allowed the Bridge, that only needs 5v DC and draws 1 Amp, to power itself from a PoE Ethernet port. Instead you need to find yet another power outlet.

But for under £20 it is possible to free up a power outlet and make use of PoE to power the Bridge.

Firstly it’s important to note that Philips changed the size of the DC socket on the Bridge. It seems as though this changed between v1 and v2. If you have a v1 Bridge the DC socket is 5.5×2.1mm and if you have a v2 Bridge the DC socket is 5.5×2.5mm.

The TP-Link TL-POE10R allows you to split a PoE input in to a separate data output and a DC output. The DC output voltage can be changed between 5v, 9v and 12v. The Bridge only needs 5v. Don’t worry about the Amps. Amps are drawn, not pushed.

The cable that the TP-Link TL-POE10R comes with has a 5.5×2.1mm male socket on either end. This is fine if you have a v1 Bridge but for a v2 Bridge a converter is needed to convert from 5.5×2.1mm (female socket) to 5.5×2.5mm (male plug). The cable it comes with is quite short, so you may need a longer cable too.
